Abstract：
The cross sections for (n, 2n) and (n, p) reactions were measured on Gadolinium isotopes at the neutron energies of 13.5—14.6MeV using activation technique. The cross section data for the reactions of ¹⁶⁰Gd(n, 2n) ¹⁵⁹Gd and ¹⁵⁸Gd(n, p) ¹⁵⁸Eu were reported.The cross sections of ¹⁶⁰Gd(n, 2n) ¹⁵⁹Gd reaction are (1940±83)mb, (2324±92)mb and (1983±77)mb at (13.5±0.2)MeV, (14.1±0.1)MeV and (14.6±0.2)MeV, respectively. The cross sections of ¹⁵⁸Gd(n, p) ¹⁵⁸Eu reaction are (1.9±0.1)mb, (2.1±0.1)mb and (3.5±0.1)mb at (13.5±0.2)MeV, (14.1±0.1)Mev and (14.6±0.2)MeV, respectively. The neutron fluences were determined by the cross sections of ⁹³Nb(n, 2n) ^92mNb reaction. The comparison was made between the present results and the previously published data.
